SWITCH.

Application filed January 5, 1927. Serial No. 159,211.

This invention relates to a circuit closer which is mainly designed for use as a horn switch on a motor vehicle and for use as a handle for the tour-way switch forming the subject matter of my application, i'iled August 20, 1925, Patent #1,612,729.

An object of the invention is to provide a compact body which may be gripped by the ngers of a hunt. of a user and in which is arranged a spring pressed button, with means for closing a circuit when the button is depressed.

Another object of the invention is to make the body 01" two sections, both formed of insulating material, and in which is located a guiding member for the shank of the push button, said member being formed of metal and connected with a tubular member pass ing through the lower part of the body and through which the conductor passes, a member of non-conducting material being ar ranged in the tubular member for carrying the contact of the conductor, said contact being adapted to be engaged by the shank of the button when the button is depressed.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claim.

in describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts through out the several views, and in which Figure 1 is a switch with the horn switch thereon.

Figure 2 is a section on line 22 ure 1.

Figure 3 is a bottom plan view.

Figure 4 is an enlarged sectional detail view through the horn switch and a part of the four-way switch.

In these views, 1 indicates the base of the four-way switch to which the metal casing 2 is attached, said casing being formed with the semi-spherical part 3 which has the cross slots i in its top. The spring contacts 5 are also carried by the base 1 and extend into the casing 52, these contacts being connected by the strips -6, as shown in Figure '3. The semi-spherical member 7 is arranged in the semi-spherical part 3 and is movable therein so that it can be rocked of Figplan view of the four-way to engage the contacts 5 A which is connected with to be moved into any one of and is adapted can be placed by the handle the member 7 metal tubular member 8 which passes through the top or the member 7 and through the spring washer 9 which acts to hold the member 7 in adjusted position through friction. The outer end 01 the member 8 is of cup shape and this cup part is enclosed by a metal cap-like member 10 which has a hole in its center. The outer part of the handle is composed of the two sections 11 formed of non-conducting mate rial, with the lower section enclosing portion of the member 8 and the upper section enclosing the member 10 to which it is attached by the screws 12. The upper or outer end of the upper section has an opening therein to receive the push button 13 formed of non-conducting material and engaging a washer 14 placed under it. said washer carrying a shank 15 which passes through the hole in the member 10. A spring 16 on the shank tends to hold the shank and the button in raised position. Non-conducting material 17 is placed in the cup-shaped end of the tubular member 8 and carries a contact 18 to which a conductor 19 is fastened,

this conductor passing through the tubular member 8 and through the casing 2 and is attached to the horn of a vehicle. A conductor 20 is connected to the shell 2 by one of the screws 21 which connects the shell or casing with the base 1.

Thus when the button 13 is depressed to place the shank 15 into engagement with the contacts 18, current will pass from the conductor 20 through the casing or shell 2 to the tubular member 8, cap 10, shank 15, contact 18 and through the conductor 19 to the horn, the current returning through the frame of the vehicle in the well known manner. lVhen the button is in raised position, the circuit will be broken, as will be understood.

Thus it will be seen that I have arranged a horn button in the handle for operating the switch member 7 of the four-way switch and thatvthehorn circuit can be closed with the four-way switch in any position.

It is thought from the foregoing description that theadvantages and novel features of my invention will bereadi'ly apparent.

I desire it to be understood that I may make changes in the construction and inthe combination and arrangement of the several parts, provided that such changes fall with ,in the scope of the appended claim.

VVhatI claim is a In combination with a four-way switch including a metal casing and a movable switch part arranged therein a handle member connected with the movable partcfor moving the same, said handle member including a tubular memberiormed of metal .a twopar t casing formed: of non-conducting material enclosing the upper end of the tubular member, a metal cap in the casing and connected"therewitlrand enclosing the up- .per end 01": the tubular member, a push button carried by the casing, a metal shank operated thereby-landpassing through a hole in the cap, a contact in the upper end of the ing the contactand. the metal-casing. v

. In testimony whereof I 'afiixmy signature.
